Revision: 10436
Log message:

      Some modifications to the DLL stuff.
        - Fixed 0-arity function calls.
        - Added some more GTK stuff.
        - Added a "target navigator" as a demo.
     This basically finishes the major backporting of the DLLs.
     
     It would be nice to implement the exploded-omake-value-to-C-value
     operation.  It is pretty straightforward, but not incredibly urgent.
